[Industrial applications]

 This invention is used for a crushing and sorting apparatus suitable for sorting a packed beverage, a packed jelly, a yogurt, and the like (hereinafter, referred to as "packed products"), and a vibrating sieve that forms a part of this apparatus. In this case, it relates to a sieve mesh suitable for treating packed jelly.

[0002]

[Problems to be Solved by Prior Art and Invention]

 In the past, when the expiration date has expired, the pack is processed by hand after the operator manually cuts the paper pack into a suitable size with a knife to remove the contents (contents) from the pack, and the contents are water ( Chemically treated and disposed of as waste.

By the way, if it is only to crush a packed product, there is a crusher or a rotary shearing crusher as described in Japanese Utility Model Publication No. 55-41309, but a packed product has contents. Therefore, crushing (cutting) the packed product is not a complete process. In other words, in the case of packed beverages, the beverages may remain in the dents of the cut pack pieces, and in the case of packed jelly, the jelly pieces and the pack pieces are mixed even after crushing, so they are incinerated. No, it cannot be efficiently disposed of as waste.

On the other hand, a screen mesh used for a conventional vibrating screen as described in Japanese Utility Model Publication No. 40-33554 is a punching wire mesh in which a flat plate 10 is simply punched out in a grid pattern to form a mesh 10a as shown in FIG. Wire mesh woven from this wire is used. With such a sieve screen, a processed product such as jelly in a pack is crushed by the above rotary shear crusher and sieved, and the jelly piece has the same cutting size as the pack piece, so the jelly piece passes through the mesh of the sieve mesh. Without it, the pack pieces and jelly pieces cannot be sorted and separated. Therefore, the jelly pieces are also mixed with the crushed pieces of the pack and transferred together, and eventually these cannot be disposed of efficiently.

An object of the present invention is to provide a crushing / sorting apparatus suitable for treating (crushing and separating / sorting) packed beverages, and also a vibrating sieve suitable for treating (separating / sorting) processed products such as packed jelly. The purpose is to provide a sieve screen.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the first invention is a biaxial shearing type crusher that cuts a packed product into a certain size by a cutting blade, and a packed process product crushed by this crusher is vibrated in a certain direction. It is combined with a vibrating screen that separates and separates the crushed pieces of the pack on the screen by using a sieve screen, and the mesh size of the screen is set smaller than the width of the cutting blade of the crusher. This is a crushing and selecting device for packed products.

In the second invention, the blade portion is formed on the upper part of the mesh member of the sieve screen installed on the vibrating screen, and the direction of the blade edge is made substantially coincident with the vibration direction of the vibrating screen. It is a mesh screen of a vibrating screen that is characteristic.

[0008]

[Action]

 By combining a biaxial shearing type crusher and a vibrating screen to ensure that the packed product is a pack shredded piece of a certain size, the packed shredded piece and the pack are packed by the sieve mesh in the vibrating screen in the subsequent process. The contents of the processed material are sorted and separated, and only the crushed pieces of the pack are left on the net and transferred in a predetermined direction, facilitating later disposal and enabling continuous crushing of the packed material. Moreover, since the crushed pieces of the pack move irregularly due to the vibration of the vibrating screen, a dewatering action of sieving off the remaining liquid components such as water and milk can be obtained.

On the other hand, the jelly piece is cut into smaller pieces than the mesh size by forming a mesh member constituting the sieve mesh into a blade shape and vibrating this in the vibration direction of the vibrating sieve. As a result, jelly pieces that were mixed in the crushed pieces of the pack pass through the mesh and fall downward, and are separated and sorted from the crushed pieces of the pack. become able to.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic side sectional view of the entire crushing and sorting apparatus according to the first invention. This crushing / sorting device is a combination of a conventionally known biaxial shearing type crushing machine A and a vibrating sieve B, and has a function of crushing a pack-processed product and then separating / sorting and transferring the crushed pieces. .

A biaxial shearing crusher A is provided above the rear end of the screen of the vibrating screen B. In this biaxial shearing type crusher A, two rotatable horizontal shafts 1 are provided to face each other, and a cutting blade 2 having a claw 2a for drawing in a packed processed object is provided on the horizontal shaft 1 along the shaft. They are closely arranged alternately. In the shear type crusher A, the size of the crushed pieces of the packing material is defined by the width of the cutting blade 2. This leads to the significance of combining the biaxial shearing crusher A and the vibrating screen B, as described later. The packed material is introduced from above the cutting blades 2 which face each other, and the crushed pieces are dropped from below onto the sieve mesh 3 of the vibrating sieve B.

The vibrating screen B has a vibration source 4 that induces linear vibration (normally 45 ° linear vibration) in an oblique direction (X direction). The vibration source 4 is composed of a pair of drive shafts 5 that rotate in opposite directions at a constant speed, and an unbalanced weight 6 attached to each drive shaft 5. A sieve screen 3 is horizontally installed in the vibrating screen body 7 so as to divide the upper and lower spaces into two parts. Further, a bottom plate 8 for transferring liquid or jelly pieces is provided below the vibrating screen body 7, and a discharge port 9 opening downward is provided at the front end. In such a configuration, when the drive shaft 5 is reversely rotated at a constant speed, an exciting force (about 5 g) is generated in a direction in which the directions of the centrifugal forces acting on the unbalanced weight 6 coincide with each other, and as a result, the vibrating sieve main body 7 has Linear vibration is applied to the installed screen 3. This vibration imparts a sieving (separating) function, a transfer (conveyor) function, and a dewatering function to the screen 3. Therefore, the crushed pieces of the pack-processed product that have fallen from the crusher A are applied to the sieve net 3 for separation and selection, and at the same time transferred to the right. If the content of the packed product is a liquid, it is almost separated when it is crushed and dropped on the sieve screen, and what remains in the pack pieces is also removed by the vibration of the sieve screen 3. (Dehydration effect). Then, the liquid that has dropped onto the bottom plate 8 flows forward along the bottom plate 8 and is discharged from the discharge port 9 at the front end. On the other hand, the pack crushed pieces are set to have a blade width of the cutting blade 2 in the biaxial shearing type crusher A so that the crushed pieces are always larger in size than the meshes 3a of the sieve mesh 3 (that is, the meshes are larger than the blade width) Since it is set small, it remains on the screen 3 and is transferred to the right by the function of the vibration conveyor to be discharged at the front part. In this way, only the crushed pieces of the pack can be collected by separating from the contents, so that the subsequent processing becomes easy.

In the case of a processed product such as a packaged beverage, the sieve mesh may have a structure in which a flat plate 10 as shown in FIG. 4 is punched to form a mesh 10a, or a predetermined mesh ( It may be a wire mesh having a (mesh).

On the other hand, in the case of a processed product such as a packed jelly, the pack and the jelly are crushed to the same size by the biaxial shearing crusher A and both are mixed, so that the sieve of FIG. Both cannot be separated by the net 3. Therefore, in this case, the sieve net 13 according to the second invention having a shape as shown in FIGS. 2 (a) and 2 (b) is used. That is, the screen mesh 13 is composed of a mesh member 13b extending in the longitudinal direction of the vibrating screen B arranged at regular intervals in the width direction, and a mesh member 13c arranged laterally at regular intervals between them. A mesh 13a having a predetermined size is formed by the members 13b and 13c. A blade portion (blade edge) 13d is formed on the upper part of the net member 13c, and the blade portion 13d is arranged so that the direction of the blade edge 13d substantially coincides with the vibration direction X of the vibrating sieve (FIG. 3 ( (See also the enlarged view of a).) The blade edge 13d is formed so as to slightly project from the upper end of the mesh member 13b in the vertical direction, so that the jelly piece can be reliably cut.

With such a configuration, the mesh member 13c having the blade portion 13d moves in the same direction as the vibration direction X of the vibrating screen, and the jelly piece on the mesh member 13c can be further cut into a size capable of passing through the mesh 13a. It has become. The arrangement direction of the mesh member 13c having the blade portion 13d is the same as the axial direction of the biaxial shearing crusher A. This allows the cutting edge 13d to run in the direction orthogonal to the longitudinal direction of the jelly pieces that are cut into strips with the crusher A so that the strips of jelly can be cut into smaller pieces than the mesh 13a size. At the same time, this is to increase the chances that the jelly piece comes into contact with the blade portion 13d. The jelly piece can be cut by the net member 13c formed on the blade member, but the paper pack cannot be cut.

[0016] Thus, the jelly pieces mixed in the crushed pieces of the pack can be cut into small pieces by the blade member and can pass through the mesh. Then, only the jelly pieces pass through the mesh and fall on the bottom plate 8 below, so that the pack pieces and the jelly pieces are selectively separated, and efficient disposal of each is possible. In this way, the tip of the mesh member that constitutes the screen mesh is sharpened to form a blade, and the blade is vibrated using the vibration of the vibrating screen to select the jelly mass from the pack piece. Efficient disposal of even jelly containing can be achieved.

3 (a) to 3 (d) show various modes of the blade portion 13d formed on the net member 13c.

In (a) to (c), the mesh member 13c itself is formed into a blade-like member by forming a blade portion 13d on the upper portion thereof, and is arranged obliquely in the vibration direction X, and the blade edge 13d vibrates. It is adapted to face the direction X 1. In (b) and (c), the upper surface (rear surface) of the net member 13c is formed into a linear shape to facilitate the sifting of the jelly pieces. (d) is a blade part 13d integrally attached to the upper part of the net member positioned in the width direction in the screen screen of FIG. In this case, the blade portion 13d may be provided also on the vertical mesh member 13b to form a laterally continuous blade portion that extends from the left end to the right end of the screen.

[0019]

[Effects of the Invention] By combining a biaxial shearing type crusher and a vibrating screen, it is possible to perform highly efficient disposal of packed products such as packed beverages and packed jellies that were conventionally done manually. be able to. In other words, since the packed products of the biaxial shearing crusher can be obtained as crushed pieces of a certain size, the packed pieces can be reliably transferred to the specified position by the vibrating screen having a mesh size smaller than this. In addition, the disposal can be performed efficiently and the continuous crushing process of the packed products becomes possible. Moreover, the dewatering effect of sieving off the liquid components such as water and milk remaining in the crushed pieces of the pack by the vibration of the vibrating screen is obtained.

If a blade portion is formed on the member that constitutes the sieve mesh and its blade edge is aligned with the vibrating direction of the vibrating sieve, it is cut into the same size as the pack piece by utilizing the vibration of the vibrating sieve. The jelly pieces can be cut into smaller pieces, and as a result, the jelly pieces mixed in the crushed pieces of the pack can be dropped from the mesh and separated and sorted. It can be processed efficiently.
